Our goal is to get closer to users and provide them the best application. We need to know what pages they prefer to enter, which ads they mostly click on, at what time and where they open our app, how they move within the app features… the more data we can compile, the better is the product we can offer. Google Analytics is a free web and mobile analytics tool offered by Google to help us analyze our traffic. In this Xamarin.Forms tutorial we are going to connect our app to Google Analytics service.



  1. Create a Firebase project.
  2. Create a simple application.
  3. Track users oppening each app.
  4. Taking advantage of Google Analytics coming soon…


Google Analytics for Firebase is a free app measurement solution that provides insight on app usage and user engagement. At the heart of Firebase is Google Analytics for Firebase, a free and unlimited analytics solution. Analytics integrates across Firebase features.



1. Create a Firebase Project

Simple: open Firebase Console and create a new project (or use an existing one).

Why Firebase? Google Analytics provide mobile app solutions across Firebase features.

2. Create simple app


I created a simple Xamarin.Forms app using a TabbedPage and a Label. Of course, you can use your own project.

3. Track your apps

We must implement the Firebase instance in each device, so this step is devided in two substeps. We are just going to track app opens.

We are not going to use any DependencyInjection.

3.1. Android

We have our Xamarin.Forms project, and our Firebase project. Also we have an Android app. Let’s start creating the app instance in Firebase.

  • If you are using a new Firebase project, just click on Add Firebase to your Android app.
  • Otherwise, go to Project Overivew and click on Add another app. Add an Android app.

Now we are going to follow Firebase steps.

  1. Complete with your app data.

    The package name can be found in AndroidManifest. The SHA-1 can be get following this guide.

  2. Download google-services.json. This file is going to be used to configure the Firebase tracking.

    Add the configuration file to the Android project: move the file into the Xamarin project, in the Android app main folder. This file must be compiled as a GoogleServiseJson. Right click in the file (in Visual Studio) and open the Build Action menu.

    Andorid compile reference

    If GoogleServiseJson option apperas, just click it; otherwise do the following:

    Right click in Android project and reveal in folder. Open Android .Android.csproj with any text editor.

    Add this to csproj Project tag. You can follow this reference.

         <GoogleServicesJson Include="google-services.json" />

    Then remove the non compiled include of the file. Also follow the reference:

     <None Include="google-services.json" />

    Now clean and rebuild.

  3. Instance Firebase in Xamarin project. 5dd09c2

    1. Add Firebase SDK: right click in the Android Package folder. The Add a Google Play service… Add Firebase.Analytics package. 161b9a3

      I always get this error when compiling:

           Message: Failed resolution of: Lcom/google/android/gms/R$string;

      I just clean and rebuild and it starts working again…

      I created an issue in GooglePlayServicesComponents on Xamarin github. If you get the same error, please react and comment.

    2. Instance Firebase Analytics in MainActivity.cs

     protected override void OnCreate(Bundle bundle)
         TabLayoutResource = Resource.Layout.Tabbar;
         ToolbarResource = Resource.Layout.Toolbar;
         firebaseAnalytics = FirebaseAnalytics.GetInstance(this);
         global::Xamarin.Forms.Forms.Init(this, bundle);
         LoadApplication(new App());
  4. Verify it’s working! Clean, rebuild and run!

3.2. iOS


As in Android, create the app instance in Firebase. Then follow the steps:

  1. Complete with the app data. The bundle ID is found in Info.plist and the AppStore ID is found in Itunes Connect after creating the app.

  2. Download GoogleService-Info.plist. This will be the configuration file.

    1. Edit the .plist file (I use XCode, but any editor is OK), set IS_ANALYTICS_ENABLED property true.

    2. Copy the file in the main iOS project folder.

    3. Right click in the file and Set BuildAction to BundleResource.

  3. Add Xamarin.Firebase.iOS.Analytics Nuget Package. Some errors will appear, you must solve them adding an mtouch argument: --registrar:static in project options. To do this open project options (double clicking the project), add the argument, and click OK.

    Important: this must be done for each compiling configuration!

  4. Instance Analytics in AppDelegate.cs

     public override bool FinishedLaunching(UIApplication app, NSDictionary options)
         LoadApplication(new App());
         Firebase.Analytics.Analytics.LogEvent("app_open", null);
         return base.FinishedLaunching(app, options);

    We are logging an event because the package is not working anything without an event raising. I also reported an issue about this.

  5. Verify your app! Clean, rebuild, and run!

4. Connect Firebase with Google Analytics

  1. Open Google Analytics.
  2. Open Admin window.
  3. Create an account (or choose an existing one).
  4. Click in + Create property.
  5. What would you like to track? A Mobile app! Se
  6. Connect to Firebase: select an app instance.
  7. Click in Connect app
  8. Everything ready! The app is tracking! Open the recently created view in top left corner and whatch the dashboard.

It’s all?

No! We are not taking advantage of Google Analytics at all… In the next tutorials I will explain how to get more and more information about our users!
